FIELD OF THE INVENTION

The present invention relates to a method of producing a sock including a gaiter (e.g., integrated into a single garment), and the sock including the gaiter.

BACKGROUND

A gaiter is a tubular element of substantially circular section used as garment in the foot and/or leg coverage of its user. A gaiter designed to cover the upper part of the shoe is also commonly referred to as polainito, the terms being considered equivalent in the scope of this document. The term in English, gaiter, is also commonly used.

This type of device aims to protect the entry of foreign bodies or liquids, namely water, earth or sand, into the shoes of its user. Is known that the entry of this type of elements causes, particularly in situations of special effort like a sports race or prolonged hiking, frictions and wear on the foot, which leads to special discomfort and even may cause wounds and ulcerations.

The document DE10226283 presents a gaiter for use in the ankle and leg that aims to protect the entry of foreign bodies or liquids, including water, soil or sand into the shoes of its user.

The document EP0852916 presents a gaiter for use in the ankle and leg, also aiming to prevent the entry of bodies or liquids into the shoe. It has the particularity of including coupling means that allow securing the gaiter around the sole of the shoe of its user, in order to prevent the gaiter to move, namely upward along the leg, which would allow the entry of said bodies or liquids.

The document KR20100095331A presents a functional hermetic sock for use on the outer side of ordinary sock, being the functional socks with the hermetic function and waterproof comprise a main body of the sock including a foot input unit, a single foot unit (60), a foot unit of the instep, a heel unit, a unit of the toe and an ankle unit. The main body of the sock is formed by molding a flexible material selected within the group consisting of synthetic resin, vinyl, rubber, and silicon.

The document JP2008006235A describes a raincoat for the foot that prevents feet from getting wet with the rain, which is prevented by said cover to act as an umbrella for the foot. This rain cover is formed by a waterproof material and has a vinyl shape slightly larger than a sock, having an insert part with a foot sheath with a pouch cord passed there through, the sheath being extensible and contractible by use of a cord, and being that the insertion part of the foot is freely effected by opening/closing sheath with cord. The clasp of the sheath with the cord allows obtaining a pouch after use, easing storage and transport. A strap with hooks and loop clasps (Velcro type) is provided in a middle portion of the sock and another belt with the hooks and loops complementary locking is placed in the lower part of the sock. The vinyl material between the two belts is very broad and it is possible to be compressed by hook and loop clasps on said belts. This foot raincoat can be used with a shoe.

The product Inov-8 Debris Sock Coolmax Gaiter identified in http://www.gearzone.com/Inov-8-Debris-Sock-Coolmax-Gaiter-p/232-14102.htm consists of a sock and gaiter integrated into a single garment, but in which the two pieces are obtained by sewing two pieces, two previously formed elements. The two pieces are sewn together in two operations, one vertical along the sock, and other circular around the cuff.

The said previous embodiments have shortcomings namely with respect to elastic adjustment, and with respect to the movements between the foot and the protection of the foot. Are particular targets of the present embodiments obtaining a superior sealing, preserving the comfort and security of its user.

SUMMARY

This disclosure describes improvements for producing a sock including a legging, a gaiter and a foot portion.

In an embodiment, a method is performed (e.g., by a knitting loom) to produce a sock including a legging, a gaiter and a foot portion, and such method is characterized by knitting the legging of the sock with a first thread until the legging longitudinally (i) extends from a starting point of knitting the legging to a predetermined point, and (ii) has a tubular form, and upon knitting the legging to extend to the predetermined point and to have the tubular form in (a), (I) securing the first thread and (II) releasing second thread to be used to knit the gaiter. Such method includes knitting the gaiter from the predetermined point with the second thread, while the first thread is secured. Thereafter, upon completing the knitting of the gaiter with the second thread, the first thread is released, and a remainder of the sock, including the foot portion of the sock, is knitted with the first thread.

DETAILED DESCRIPTION

Describes a method of producing a sock including a legging (1), a gaiter (2), and a foot portion (3). A sock usually comprises a legging of the sock and a foot of the sock.

In the present embodiments, the sock can include the gaiter (2) along the sock circular section between said gaiter (2) and said foot (3) of the sock, the sock including the gaiter (2) being integrally formed in a single garment, in particular integrally formed in a single garment by knitting.

This gaiter (2) should have enough circular cross-section to be able to countersink until covering the shoes of the user.

Through the inherent elasticity of the sock and gaiter (2), namely in the elasticity of its circular section union, one can obtain a piece especially adaptable and able to keep in proper position to prevent the entry of foreign bodies or liquids, namely water, earth or sand to the inside shoe of its user, even under conditions of high effort and movement by the user. As usually liquid or foreign bodies originate from the soil, this type of elastic adjustment, which avoids vertical movement while being coupled to legging (1), allows a superior sealing and preserves the comfort of its user. These effects are particularly enhanced the sock and gaiter being integrally formed in a single garment, in particular if integrally formed in a single garment by knitting.

The capacity of the gaiter (2) going down or up (FIGS. 1A and 1B) is particularly convenient. In the lowered position (FIG. 1B), the gaiter (2) protects the entry of said bodies or liquids, and in the raised position (FIG. 1A), the gaiter (2) allows shoes to be easily put on or taken off, allows contamination from retained, accumulated soiling to be avoided, and allows larger breathability for the shoes.

This way, the user obtains a piece with a superior performance to traditional gaiters, at the same time that it obtains a more practical piece and of more flexible use.

In one embodiment (e.g., FIGS. 2A and 2B), the gaiter (2) includes gripping means which allow narrowing the circular section of its extreme, so as to achieve an even better fit.

In one embodiment (e.g., FIGS. 3A and 3B), the gaiter includes an elastic cord in its circular section, at its periphery, so as to achieve an even better fit.

In one embodiment (e.g., FIGS. 6A and 6B), the gaiter (2) comprises two coupling means placed substantially opposites on the circular section of its extreme, substantially on opposite sides of the shoes (5), for coupling with each other, under the sole so as to achieve an even better fit. In particular, one can use springs or metal hooks. In alternative, the two coupling means can engage the shoes (5) itself, especially, if the shoes (5) itself provide elements complementary to this coupling, in particular molded on the side of the shoes sole. In a particular embodiment, these coupling means are joined to the gaiter by said gripping means, in particular a cord at the end of the circular section of gaiter.

The length of the legging may be variable, as to the knee, thigh, or even pantyhose, for reasons of comfort or depending on the intended use.

The length of the gaiter may also be variable, provided that it permits adequate protection for the entry of materials and fluids in the shoe.

The joints between materials of the sock/gaiter/coupling means may be obtained by sewing, knitting, gluing, Velcro coupling, among others.

In one embodiment, the sock and gaiter are integrally formed already joined together in a single piece, in particular through molding.

In one embodiment, the sock and gaiter (2) are integrally formed from the same piece (see ex. on FIG. 5) to later the circular part being joined along a circular section so as to define the parts of the piece sock and gaiter. The union of the circular piece, previously integrally formed, can be obtained by sewing, knitting, gluing, Velcro coupling, among others.

In one embodiment, the sock and gaiter (2) are integrally formed from the same circular piece by knitting, i.e., seamless.

In one embodiment, the sock and gaiter (2) are integrally formed from the same circular piece by knitting, being that textile materials used in knitting are alternated so as to obtain differentiated materials for legging, gaiter and/or foot of the garment, which has the advantage to adapt itself to the garment to different uses or purposes, according to the material chosen for each part, e.g. using tougher wires or more elastic according to the party concerned.

In one embodiment, the sock and gaiter (2) are integrally formed from the same circular piece by knitting, so that the knitting of gaiter is tighter than that of the legging or foot, that is, the intervals of the knitted mesh are smaller. This has as advantage to prevent the entry of foreign bodies on the gaiter, e.g. grains of sand, smaller than the interval of the knitted mesh of the legging or foot, while allowing greater comfort and breath of the legging or foot through the wider mesh, and therefore more flexible.

In one embodiment, the gaiter (2) or the gaiter (2) and the remainder of the sock are waterproofed fabric, in particular by adding water repellents, e.g. silicones.

In one embodiment, the gaiter (2) when raised, can be used to collect objects, in a pocket function. It can contain cooling elements, such as gel packs or cooled liquid, especially useful after intense physical effort to prevent injury and accelerate physical recovery. It may contain electronic devices, such as biosensors, processing devices for biometric data, or even a mobile phone.

The materials that can be used on legging, gaiter and/or foot include: Cotton, Organic Cotton, Wool, Silk, Polyamide, Polyester, Milk Fiber, Soy Proteinaceous Fiber, Seacell®—cellulosic fiber obtained from algae, Bamboo, Nettle fiber, Maize fiber PLA, Trevira Bioactive®—polyethylene terephthalate, Dri Release®—mixture of 85-90% hydrophobic material/synthetic and 10-15% natural/hydrophilic material, Coolmax®—polyester fibers with recesses along the fibers in tetrachannel configurations or hexachannel, Cocona®—fiber as from activated carbon from coconut shells, DreamFel®—polypropylene, Viloft®—rayon, regenerated cellulose fiber, Crabyon®—Chitin/Chitosan, Amicor®—fiber with functional compounds in its interior Meryl Fibre®—polynosique, viscose fibers, TACTEL Fibre®—light nylon fiber, X-Static®—fiber incorporating silver.

The sock can be of textile, woven or non-woven, in particular knitted or sewn by segments.

The present application discloses a process, performed by a knitting loom, to produce a sock including a legging (1), which can be in tubular form to accommodate the lower leg of the wearer of the sock, a gaiter (2) and a foot portion (3), as shown in the flow chart of FIG. 7. In such process, the knitting starts at the sock handle (13) with the knitting of a circular section, and develops in a circular manner towards point (12) (step S71).

According to the type of sock to be made, the loom is suitably programmed so that at point (12) in the knitting process, the set of needles (e.g., cylinder needle 7, latch needle 8) of the loom secures the fabric already made in the legging (1) and at the same time releases thread for the knitting of the gaiter (2) (step S73).

This operation is possible because the knitting loom, including the set of needles (e.g., cylinder needle (7), latch needle (8); FIG. 10), is able to handle at the same time the first threads (10) which produced the legging (1) and the second threads 11 which are to knit the gaiter (2). That is, while releasing (e.g., supplying) the second thread (11) to begin the knitting of the gaiter (2), the knitting loom secures the first thread (10) which knits the legging (1). The knitting of the legging (1) with the first thread (10) can be suspended by, for example, cutting the first thread (10) (e.g., with a blade or a knife included in the knitting loom), when the second thread for knitting of the gaiter (2) is supplied.

The process further includes knitting of an excess of fabric, which is the gaiter (2) (step S75). The end point of the knitting of the gaiter (2) may lie precisely in the same line as the knitting of the gaiter (2) started, in point (12). Upon completion of the knitting of the gaiter (2) with the second thread (11), the set of needles (e.g., cylinder needle (7), latch needle (8) of the loom releases the part of the sock previously secured (e.g., the first thread 10) in order resume the knitting of the remaining sock and the foot (3) (step S77). The knitting of the gaiter (2) can conclude when the second thread (11) is cut (e.g., with a blade or a knife included in the knitting loom), and the knitting of the legging (1) can then resume with the previously secured first thread (10).

The point (12) in which the gaiter (2) will start being knitted is determined by the height of the footwear with which the sock with gaiter will be used.

In one embodiment, as seen in FIG. 9, point (12) is closer to the sock handle (13) in order to use the sock including the gaiter (2) with a boot.

In one embodiment, such as in FIG. 8, the point (12) is located at a height that allows for the use of a regular shoe.

The use of cams, which are needle paths, with specific designs, special technical knitting programs and specific yarn containment devices, while knitting the gaiter (2), allows to guarantee the production of the sock and gaiter integrally without any complementary operation.

The final product is a single piece of fabric without stitching, appearing seamless.

As can be observed in FIG. 10, which shows the knitting elements of the loom, the legging (1) is knitted initially with first thread (10). The legging (1) is knitted until it reaches the beginning zone of the gaiter (2), which is point (12), then the first thread (10) stops being fed to the needles and it is retained in the back of sinker (9) and out of the knitting zone until the knitting of the gaiter (2) with the second thread (11) is finished. When the knitting of the gaiter (2) is finished, the rest of the legging (1) and the foot (3) are knitted with the first thread (10) and the second thread (11) of the gaiter (2) can be cut off and no longer fed to the needles.

To allow this operation, the two threads (10),(11) are in the needles (e.g., cylinder needle (7), latch needle (8)), but the second thread (11) which will knit the gaiter (2) is closer to the latch (6) than the first thread (10) which knits the sock leg (1). During the knitting of the gaiter (2), the range of the movement of the latch needle (8) allows for the second thread (11) to be released while the first thread (10) is secured. When the knitting of the gaiter (2) is complete, the second thread (11) can be cut off, and the movement of the needles (e.g., cylinder needle (7) and/or latch needle (8)) releases the first thread (10).

The latch needle (8) may be a conventional latch needle, such as, for example, latch needle (20) shown in FIG. 11 (Errol Wood, Machine Knitting, 2012, WOOL482/582 Wool Processing, citing Wood, 2010) which is commonly used in weft (e.g., horizontal, cross-wise threads) knitting. In such arrangement, the latch needle (20) includes a hook (15), latch (16) [including latch blade (16 a), latch spoon (16 b) and pivot (16 c)], a stem (18), a butt (14) and a tail (19). The hook (15) is configured to receive thread supplied to the needle, and the latch needle (20) is advantageously self-acting or loop controlled in that the stitch or loop initially in the hook (15) can move along the needle to open and close the latch (16) [as the latch blade (16 a) and the latch spoon (16 b) rotates back and forth about the pivot (16 c)] during knitting. A stitch or loop may be formed by way of a conventional process, employing such a latch needle (20), such as shown in Figure (Errol Wood, citing Wood, 2006). In step S121 a previously formed stitch or loop is present in the hook (15). When the hook (15) is in a closed configuration, the latch spoon (16 b) extends from the latch blade (16 a) to contact the hook (15) at position B.

In step S122, when the latch needle (20) is lifted such as by way of a cam (not shown), which interacts with the butt (14) protruding from the stem (18) to enable movement of the needle, the previously formed stitch or loop in the hook (15) moves along the latch needle (20) to open [i.e. the latch spoon (16 b) extending from the latch blade (16 a) rotates, clockwise in the view shown in FIG. 12, to the position A] the latch (16) and is moved to the stem (18) of the latch needle (20) to a clearing or rest position. In step S123, the thread or yarn to be used for the next stitch is retained by the hook (15), while the latch (16) remains open and the previously formed loop or stitch remains on the stem (18) of the latch needle (20). In step S124, when the needle is moved downwards, such as by way of the cam via the butt (14), the previously formed loop or stitch is configured to close [i.e. the latch spoon (16 b) extending from the latch blade (16 a) rotates, counterclockwise in the view shown in FIG. 12, to the position B] the latch (16) when it is moved along the latch needle (20) towards the hook (15), and such previously formed loop or stitch falls beyond the hook (15) over the new stitch received by the hook (15) in step S123 to form another loop or stitch. In step S125, the latch needle (20) is then ready to form another loop or stitch (such as in step S121).

A conventional sinker (131), such as shown in FIG. 13 (Errol Wood 2012, citing Wood, 2010) may be employed. The sinker 131 may be a thin piece of metal and can be placed at 90° to a needle bed (e.g., FIGS. 14A-14C), and can be fixed to a bar, or held on an end of a pivoting lever. The sinker (131) can be disposed between adjacent needles to facilitate formation of loops from thread or yarn laid across the needles, and can cause loops to be moved on and off the needles. The sinkers (131) are commonly used to hold already-formed stitches or loops at a lower level on the needle stems than a level at which new loops are being formed, and prevent the already-formed loops from being lifted as the needles rise, to clear the already-formed from their respective hooks.

As discussed, the sinker (131) can be placed at 90° to a needle bed, examples of which are shown in FIGS. 14A-14C (Errol. Wood 2012, citing Wood 2010), on which needles are fixed at certain distances from each other in order to guide the needles during the knitting process. To achieve this control, the needles are placed in slots called needle tricks on the needle bed. The needle bed can be circular, such as a cylinder needle bed (141) [FIG. 14A] or disc (or dial) needle bed (142) [FIG. 14B], or can be a straight or flat needle bed (143) [FIG. 14C]. The needle tricks are machined parallel to the axis of the cylinder in a cylindrical needle bed (141), and point towards the center of the dial in the dial needle bed (142). The cylinder needle (7) (FIG. 9) can be, for example, a cylindrical needle (144)[FIGS. 13 and 14A] included in the cylindrical needle bed (141).

The aforementioned knitting loom can be, for example, a conventional single jersey knitting machine, a conventional double jersey knitting machine, or another knitting loom. The double jersey knitting machine is a single jersey machine with a dial needle bed (152) [such as, e.g., shown in FIGS. 14A and 14B], which can house an extra set of needles, such as latch needles (20), positioned horizontally, adjacent to, for example, vertical cylinder needles (144) in a cylindrical needle bed (151), such as shown in FIGS. 15A and 15B (Errol Wood, citing Wood 2010). Such extra set of needles can enable production of fabrics twice as thick as those produced by a single jersey knitting machine, and can enable enhanced design possibilities. The needles in the dial needle bed (152) can knit an inner face of the fabric and the needles in the cylindrical needle bed (151) can knit an outer face of the fabric.

Both the size of the gaiter (2) and the extensibility of the yarn resulting from the knitting process are parameterized by loom programming.

The loom in which the sock with gaiter is produced can be a single cylinder loom used in this area of practice comprising a set of needles (e.g., cylinder needle (7), latch needle (8)) commonly employed in such looms.

In one embodiment the sock with the gaiter is produced in the same type of material.

In another embodiment, the sock is produced in a different material than the material used to produce the gaiter.

In one embodiment, when the material of the gaiter is different from the material of the remaining-sock, the loom comprises a different wire guide to knit the gaiter.
